Abstract

A fieldbus type of distributed fire alarm control system based on single chip microcomputer MCS-51 is introduced.This system possesses features as follows:Most basic logical original types are expressed as simple machine languages,constructing a fine men-machine interface;Fieldbus structure is adopted,making network integration be implemented easily;The method of synchronous count-sequential capture multi-access is adopted in network communication,freeing central unit from roll-polling regional units,and improving level of system distribution,and enhancing utilization factor of equipment.This system is flexible in structure,convenient for use,it will meet the needs of all kinds of fire alarm and fire control.
